algebra 1 honors- combining like terms problems

Hello Rebekah,

Only the coefficients will change in value.

here, **just add the coefficients, of the same variable**, taking into consideration the** sign
**also.

the coefficients are -1 and +12; when we add those two , we get +11

Let me give you another example.

Simplify (-5x+8y+12x-19y)

we have two variables here x and y

first take the coefficients of x; -5 and +12. Adding them will give you +7

Noy coefficients of y; +8 and -19. Adding them will give you -11

so the resulting expression will be 7x-11y

Hope this helps.
